closurein javascript is a feature where an inner function retains access to variable of it's outer function.Even after that outer function has finished executing.
EXAMPLE:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<script>
function bank() {
let min_balance = 500;
const actions = {
deposit: function (amt) {
min_balance = min_balance + amt;
console.log("current balance is ",min_balance);
},
withdraw : function(amt){
min_balance = min_balance - amt;
console.log("current balance is ",min_balance);
}
}
return actions;
}
const check_bla = bank();
check_bla.deposit(220);
check_bla.withdraw(500);
</script>
